oomom class ofinechan'icallyo UNITED STATES JAMES H. LUX, OF'THOMPSONYALLS, MONTANL ELECTRIC-CIRCUIT BREAKER.

To all whom it may con/cent:

Be it known that 1, James H. Lux a citizen of the United States, residing at 'fhompson Falls, in the county of Sanders, State of Montana, have invented certain new and useful Improvements in Electric- Circuit Breakers; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to an electric circuit breaker and more particularly to the perated switch opening and closing mechanism.

The primary object of the invention is, I

the provision of mechanism of this character, wherein several or any number of knife switches for controlling electric circuits can be automatically opened and closed for the controlling of the elcctric current or currents to and from a sign or other electrically operated device, the mechanism being of novel form to assure the positive opening and glosing of the switches.

Another object of the invention is,'the provision of mechanism of this character, wherein the electric switches are mounted in a. novel manner and automatically controlled-for the opening and closing thereof during theworking of said mechanism.

A further object ofthe invention is, the provision of mechanism of this character, which is simple in construction, operative for the automatic opening and closing of electrie' switches, thoroughly reliable and ellicient in operation, ositive in action andv inex ensive to menu acture and install.

. ith these and other objects in view,'the invention consists in the. features of construction, combination and arrangement of arts as will be hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended;

In the accompanying drawingz' Figure 1 is an elevation of the electric circuit breaker mechanism constructed in accordance with the invention.

Referring 'to the drawings in detail, A, designates generally the base of the circuit breaker mechanism, from which rises spaced vertical uprights 10 and 11 respectively, the 1 upright 10. being formed with an upper fork end 12, the arms of which are provided with vertical slots 13 in which is movably sup ported a bearing block 14 carryin a horia zontal spindlelo. Acting upon t is block 14 are adjusting screws 16 which are mounted in a stationary bridge l'ijsecu'red in the closed ends of the slots 13, the Screws-'16 being titted with binding nuts 18, through thg medium of which the bearing block can a be raised or lowered in the forked upper end 12 of the upright it) and held in adjusted position by a set screw 16 fora purpose presently described. i

The upright 11 is of considerably less transversely in these uprights is a horizontal shaft 19, on which is mounted a driving belt wheel 20 adapted to have trained thereover an endless belt 20' which is driven from a motor 21' preferably of the electric ty e a of any suitable construction adapted to e started and sto ped in the usual manner by a switch. A so carried by the shaft 19, is a belt pulley 21, over which is trained an endless belt 22, the same being also traiuedil'flf over the peripherally grooved pulley ring 23 of a cam carrying whelQtL-ivhich is fixed to or journaled on the spindle-i5, toyi; rotate the wheel 24 for a purpose presently described. Mounted upon the upright ii for vertical, adjustment, is an inverted substantially E3: shaped bracket 25, while mounted upoii.the p bearing block .14 and overhanging the bracket 25 is a hanger 26, and connected to 16!) said brackct and hanger forwardly of and carrying. v

wheel 24, is a ring 27 which may be tubular or a plane band, carr ing' thereon one or a.

plurality of electric rnife switches 28 for opening and closing one or more electric circuits of electric flash signs or the like; it being understood that each switch is connected to the source of energy and a'signor part thereof or other suitable device to be illuminated or operated. The conductor wires may be suitably trained through the in 27 and are connected with the JOStS O and 31 respectively, of said switches, the handle end 29 of the knife of the switch 28 being extended forwardly toward the outer face of the cam carrying wheel 2% which has arranged thereon diametrically opposed or otherwise suitably spaced rerersely set and acting cam protuberances 32 and 33 respectively, adapted to successively engage the handle end of the switch'knife or blade for the opening and closing thereof automaticallv on the rotation of the cam carrying wheel 24, and thereby make and break the circuit in the opening; and closing movement of the switch, as will be clearly obvious.

The adjustment of the. bearing block 14: and the wheel 24radially of the ring 27 can be had with accuracy for the proper positioning of the cams 32 and 33 respectively, with respect to the switches to assurepositiveness in the operation of the circuit making and breakingmechanismm As shown,

the cams 32 and 33 areilocated at different distances from the axis of the wheel 24, the cam 32 being located at the peripheraleduc and serving to move the switcp handle 29 inwardly on its pivot, while tl ecam 33 is spaced inwardly from the peripheral edge of the wheel to move the switch handle outwardly. To facilit-ate this operation, the cam 32 is directed outwardly'slightly while. the cam 33 is isimilarly directed inwardly so as to strike and deflect the handle in eac i instance, as they pass by the handlc,-irresptictive of the number of switches employed and the number of (turns employed, and the relation of the latter relative to each other circumferentially. f

Clamping screws are engaged through vertical slots in thci lvertical portion of the bracket 25 and withf'lxthe upright or stand ard'll, so that the li 'acket can be adjusted vertically and held in adjusted position on the upright. lllsoyt trtmgh the vertical adjustment of the-bloci i 14: the wheel 24 may be shifted toward and'a'way from the pulley 21 so as to properly ai ljustthe belt 22.

It is also to be undo 'stood that in lieu of the knife or singleltlugow switches 28, any other desired or a zgprtb vcd form of switch may be employed. such as a ,goose neck or 1 double throw switch 28' so that upon actuation of the knife orgblade thereof, the blade will move out- 0f (lonlact atone side and into contact at the other side to open one circuit and close the other, as is the purpose for which such switches are intended. Any number of arms may be provided on the portion of the hanger 26 where anchored .to the bearing block l i for supporting the '70, ring 27, and'further any other changes may be made in the construction and relation of i I v the parts as come within the seopeof the device as claimed.

It will be seen that the mechanism is useiful for controlling electric signs or other; electrically actuated devices and will sue-J cessfully serve to open and close electric cir cults, it being, obvious that any number of circuits may be controlled, as a plurality of switches can be mounted upon the ring27 to arrive at this end andtliereby meet-differing conditions iu theuse of the mechaoperable'upon the knife switch to successively open and close the same.

2. The combination with an electric knife switch, of a ring having the/switch mounted thereon,a bracket connected with said ring, a rotatable carrier having cams o-perabledOO upon the knife switch to successively open and close it, a standard by which the cam carrier is supported and a second standiu d with which said bracket is adjustably' con nected to position the ring in axial alin'ement with the carrier. a 3. The combination with an electric knife switch, of a ring having the switch mounted thereon, a support, a cam carrier rotatably carried by the summit and-having cams op! 11 0 erable upon the knife switch to smcessively open and close them, a second support V bracket carried by the second support and upon which the ring is mounted, the bracket being adjustable on the support to axiallyilo aliue the rinp with the camcarrier, and

means carried by saidsupports and connect ed with the cam carrier for actuating it, j a 4.
